Since the beginning of the sewage of the world was a concern. Human waste has always been an unavoidable problem in any society. Because of the stench of different companies that came with the purification of the divers in an attempt to improve the quality of their lives. It all started with people who refuse buried in the ground and has since developed to the point that entire cities and even countries are connected to large systems for this purpose.
Different elements are wastewater, such as gray water and black water. Grey water includes water used for washing, bathing and washing. Black water includes water containing feces and urine. Runoff of storm water can also be considered sewage.
The first form of treatment has been used to bury the waste underground. The covering so that the waste may be absorbed directly into the ground. With groups of people who moved around a lot hunting and gathering was a very efficient plan. It’s always a good method for camping in the desert today.
The intuitive solution for groups of people who have settled in a place was to dig a bigger hole to contain the waste. The larger hole would give pride of place for waste prevention and other areas to be disturbed by the waste. By building a shelter around the pit that they made more attractive and pleasant. They tended to be at a distance from where the living space was in order to avoid the smell. They are known under different names such as toilets or pit latrines. They are still used as a solution in the sewer campsites. The port-a-pot is addictive modern.
Major cities before modern plumbing, with their wastewater treatment systems treated by a simple throw it out the window into the street. This is still practiced today in some places in the world. As this practice may be detrimental to the house, leaving open sewers where people can inhale it, it would be healthier to live somewhere in the country where it is practiced in the city. This is one of the arguments suggested to explain why a man walked out of a street when a woman in order to avoid having the woman splashed by accident.
In modern cities today, the systems of wastewater treatment used today is either centralized or decentralized. Decentralized treatment of wastewater is treated close to where it came from. Central Processing is it addressed in a central plant there after transporting pipes.
Wastewater plant goes through the different levels of treatment. Gravity and filtering the solids are removed. Then the micro-organisms decompose the waste. Depending on the level of sophistication in a plant of the water that is released at the end of treatment may be drinking.
Those who are not connected to a municipal sewage system mainly use septic tanks. A septic tank works by having the solids settle to one side of the tank and pumping filtered liquid to a pipe in a waste area where they can be absorbed by the soil.Septic tanks are even more effective by adding microorganisms in the tank to aid in the treatment of solid waste.
Anyone who lives and breathes is affected by sewage, it’s just a fact of life. Over the years she was treated with a variety of ways, but it is clear that in order to have quality of life that we must take care of some sort.
